4. The method of claim 1, wherein the transmitting occurs via a mobile device in data communication with both the Internet of Things device and the server.

5. The method of claim 4, wherein the mobile device is in data communication with the Internet of Things device via a Bluetooth connection.

6. The method of claim 4, wherein the mobile device is in data communication with the server via a Wi-Fi connection.

7. The method of claim 1, wherein the transmitting occurs directly between the Internet of Things device and the server via a wireless network connection.

9. The method of claim 8, wherein the device certificate received from the Internet of Things device is validated at the server against a certificate issued by the manufacturer of the Internet of Things device.

10. The method of claim 1, wherein the first challenge comprises a first random number challenge.

11. The method of claim 1, wherein the first response is the first challenge signed with the private key associated with the Internet of Things device.

12. The method of claim 2, wherein the second response is the second challenge signed with the private key associated with the server.

14. The method of claim 13, wherein transmitting the random number challenge to the server comprises transmitting the random number challenge to a mobile device for forwarding to the server.

15. The method of claim 13, wherein verifying the signed certificate comprises decrypting the signed certificate using a public key of the server at the electronic lock.

17. The method of claim 16, wherein, based on the first signature result and the second signature result, communication is enabled between the electronic lock and the cloud server.

18. The method of claim 17, wherein, upon authenticating the cloud server at the electronic lock and authenticating the electronic lock at the cloud server, the electronic lock is enabled to communicate with the cloud server via a Wi-Fi connection without requiring intermediation by the mobile device.

20. The electronic lock of claim 19, wherein, upon completion of the authentication process, the electronic lock is enabled to receive a command from the server to actuate the motor and drive the latch between the locked position and the unlocked position.
